Jul 5, 2012 at 22:20 comment added Lee Mosher If we had to grant someone a license to formulate a mathematical definition of an electron, it would have to be a particle physicist, who at least has the necessary intuitive physical understanding. Similarly, if we had to grant someone a license to formulate a mathematical definition of music, it probably should be an M.D. Psychologist/Biophysicist who plays in a subprofessional string quartet. But a mathematician.....
Jul 5, 2012 at 20:19 comment added David Feldman I agree, philosophically speaking, mathematics doesn't answer "what is an electron." But it would not surprise me to hear a physicist say "well, actually, an electron is a representation of this-or-that group" or "...an equivalence class of sections of this-or-that sort of vector bundle." For that matter, if you know Feynmann's "I don't even believe in the inside of a brick," electrons are perhaps only theoretical entities (so fundamentally mathematical) that physicists invented to explain more concrete things.
